OK, I'm a total newbie to diesels, go ahead and laugh at me. Well not totally new, I used to own a 1984 Ford Escort diesel LOL. Now you may laugh.
Anyways, I just bought my first powerstroke, it's a 2001 F-350 with 263K on it. My question is, do the injectors ever make a tapping sound that sounds like a lifter ticking? It's a distinctly different sound than the diesel sound. I only hear it occasionally at idle, it seems to go away as soon as a little throttle is applied. It is driving me crazy! It has good oil pressure, can't say how many pounds as I only have the factory L-H gauge, but is about 2/3 of the way up the normal range. I just changed oil using Royal Purple synthetic and a K&N filter and the occasional tapping persists. If this is normal I can easily ignore it, I just don't want to ignore impending motor failure.Thanks in advance for all opinions.

Ya mine tick I know exactly what ur talking about mine stops doing it as soon as I hit the throttle. Some may say ur injectors are gone but mine does it and my injectors are fine starts up in the cold without a problem. And trash that k&n filter or try to return it for the same price as that k&n u could of got a 6637 filter that's what most of use on here run its just a huge filter. Just do a quick search of 6637 intake

I guess I should have been more specific. I meant a K&N HP6001 oil filter. Why are the K&N air filters so frowned upon? Remember I am a total newbie to this diesel truck thing

The k&n air filters let to much particles of dirt and dust in so eventually all that dirt and and dust will eat away at ur turbo. A good way to tell if ur turbo has had alot of dirt go through it is to take the intake off and look at the turbo wheel if it is pitted and scratched its had a dirty life will
Need to be replaced in the future it's called a dusted turbo.

If the sound really is driving you crazy then then this is probably the cheapest thing you can add to your truck to take care of most of the noise at idle.

It sends a constant flow of fuel threw the heads and alleviates most of the lifter sound or "cackle" that can be heard from the #8 injector.
Btw, K&N oil filters have the same element as the Mobil1 filters, so which ever is cheaper.......
